Hallo
Using 3D tetrahedral elements, with what minimum wedge or sector (included) angle would you, generally speaking, still feel comfortable to analyse an axisymmetric problem? 15°? I realise it depends…, and might vary; but surely there must be some rule of thumb to generally deliver robust results (almost code-like).
I still very much prefer using proper axisymmetric elements (especially for non-linear) but most “designer” packages does not offer it, and at the same time computing capabilities also got better.
Thanks
Regards
